In scientific terms, a fruit is the ripened ovary of a flowering plant. They generally consist of a protective membrane outside of one or more seeds. The purpose of the fruit is to help the plant spread its seed to new areas where new plants can grow. The outside layer of skin helps protect the seeds from weather, predators, and other forces of nature that could hinder the plant’s reproduction. Fruits also happen to be incredibly delicious.

Fruits that start with O include any flowering plant ovary that has a name beginning with the letter “O”. Chances are, you’re already familiar with the orange, which is ranked number 4 in terms of global fruit production. There are also some fruits, such as the opal plum, which are variations of fruits that don’t typically start with the letter “O”. Finally, there are a couple of fruits in the list that you may be surprised to learn are not vegetables.

Common Fruits That Start With O

  1. Orange – Originally derived from a combination of mandarin and pomelo fruits, the sweet orange has been a delicacy since at least 314 BC. Orange trees are primarily grown in tropical regions and it’s believed they are the most common fruit tree in the world. Orange is classified as a citrus fruit similar to lime, lemon, and grapefruit. It is both sweet and acidic, though not nearly as sour as other citrus fruits. This makes it an excellent addition to many different marinades.
  2. Okra – If you enjoy cooking, then it’s probably impossible to convince you that okra is actually a fruit. It looks like a vegetable and it lacks the sweetness of a fruit, but scientifically it is classified as a fruit. Okra pods are the ripened ovary of the Abelmoschus esculentus plant. While it may technically be a fruit, you probably won’t enjoy biting into a slimy, raw okra pod like you would an apple.
  3. Olive – This is another common fruit that can surprise some people. They are a type of fruit known as a drupe. That category also includes peaches and plums. If you’ve purchased jarred olives from the store, then it’s likely their original seeds were removed and replaced with another fruit called pimento.
  4. Opal Apple – Opal Apple is a type of apple that was developed in Europe and is now grown in the United States. It is a medium-sized apple with a yellow skin that is sometimes blushed with red. Opal apples are known for their sweet, juicy flavor and crisp texture. They are a good source of dietary fiber, vitamin C, and antioxidants, which help protect the body from damage caused by free radicals.
  5. Orient Pear – Orient pear is a type of pear that is known for its large size and sweet flavor. It is a winter pear and is harvested in late summer or early fall. Orient pears have a round shape and a yellow-green skin that is often blushed with red. They have a juicy, tender flesh that is white in color and has a sweet, mild flavor. Orient pears are a good source of dietary fiber, vitamin C, and copper. They are also low in calories and contain no fat or cholesterol, making them a healthy addition to any diet.
